1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Ammonia has attracted great attention as a key material for clean hydrogen production, such as the ammonia cracking process. Remaining trace ammonia in the purification step is considered a critical impurity due to its toxic and corrosive nature. Herein, we introduce ammonia as a tuning agent for MOF membranes to control their gas transport behavior. When exposed to ammonia, the ZIF-8 membrane undergoes partial surface amorphization due to strong interactions between ammonia and the framework, while the adjacent ZIF-8 region becomes rigid. As a result, the ammonia-treated ZIF-8 membrane exhibits the intrinsic gas-selective property rather than the flexible one, yielding excellent H
